How to revolutionize city-data forums?

[TravelChange2012]

I really enjoy City-Data FORUMS as a resource and I think there's plenty of room for improvement. My question is this:

How can city-data FORUMS aspect be improved through a desktop/mobile/tablet application? What significant value or features or functions can be added that would make the forum aspect tremendously more valuable?

*Other than simply making it a mobile app and/or making it mobile design friendly.

If CD could provide a Replicator app so my phone could generate a tuna and swiss on rye, I would be ecstatic.
